Noinexu Shore track is broken on mobile

[woosh]

When I tried to play the Noinexu Shore track on mobile STK, some parts of the track are missing (e.g. the sand bridge you normally go under right at the beginning). That way, it's impossible to follow the normal drive path. The AI karts try to do it anyway and go off track right away. You can complete a whole lap but the lap is much shorter than its supposed to be and the game play makes no sense.

Has anyone else noticed this problem?
Can anyone fix it, please?
